- The Control Voice: Humankind has long tried to tame the forces of nature, to harness their power for our needs. But what if the very needs that drive us are the greatest power of all? Will we be able to control ourselves?
When a woman gets possessed by an alien, she goes around seducing men and killing them.
- The Control Voice: The urge to hunt and kill — the need to mate and multiply — these are our most primitive human drives. But they pale in comparison to the most powerful human drive of all... the need for love.

- Girl-on-Girl Is Hot: A sleazy detective taunts the male protagonist and says his girlfriend is a slut (she's been infected with an alien parasite which sucks out people's lifeforce through sex). He angrily retorts that she would never cheat on him. The detective goes, "Oh yeah? According to her roommate, she goes both ways!" The boyfriend says eagerly, "Really?"
- Horny Devils: An alien parasite causes Hannah to become a hypersexual life-sucking succubus who swings both ways.
- Intimate Healing: A variation occurs where the way to get an alien that kills men through sex out of the female host's body is by having sex (well, starting to, anyway) with her boyfriend. The explanation is that "love" was what the alien was really looking for in the first place so when it experiences that through the host's contact with her boyfriend, it can finally leave her body.
- Not Right in the Bed: This episode features Alyssa Milano as a pure, virginal woman...who is possessed by an alien entity that feeds by seducing and devouring men.

- Rage Against the Reflection: Hannah is possessed by an alien and goes around seducing people, then eating them after sex. In the girl's bathroom, she loses her temper after the alien tries to seduce her roommate and punches the mirror. She then picks up a shard and attempts suicide, but the alien regains control and makes her drop it and continue its mission.
